FILM-PACK HOLDER FOR CAMERAS.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed June 26, 1907. Serial No. 380,860.

T 0 all whom it may concern:

Be it known that I, ALBERT H. I/VRIGIIT, a citizen of the United States,residing in Quincy, in the county of Norfolk and State of Massachusetts,have invented an Improvement in Film-Pack Holders for Cameras, of whichthe following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing likeparts.

This invention relates to a film pack holder for use in cameras, and hasfor its object to provide the holder with means as will be described,whereby difierent sizes of films may be used in the same camera.

As now commonly practiced, a plurality of films are assembled togetherin the form of a pack, each film having a projection or tab by which itmay be removed from the pack holder, which latter as now commonlyconstructed is made of a size to fit the pack of films and is providedwith a removable shutter or slide, and with an opening in its topthrough which the tabs on the films pr0- ject, so as to be accessible tothe operator and enable him to remove the films one by one, after theyhave been used.

The present invention has for its object to provide pack holders of theclass described with means for permitting the holder to be used withfilm packs of different sizes as will be described. 'These and otherfeatures of this invention will be pointed out in the claims at the endof this specification.

Figure 1 is a front elevation with parts broken away of a film-packholder embodying this invention. Fig. 2, a side elevation of the holdershown in Fig. 1, with the back partially opened. Fig. 3, a cross-sectionon the line 33, Fig. 1. Figs. 4 and 5, details of the removable frame orholder to be referred to. Figs. 6 and 7 modifications to be referred to,and Fig. 8, a plan view of the holder shown in Fig. 1.

Referring to the drawings, I have shown the invention as embodied in apack holder of ordinary construction and consisting of an open framehaving side bars a, 6, connecting top and bottom bars 0, (Z, a removableback 6 hinged at its lower end to the bottom bar (Z and secured in itsclosed position by clips or levers f, and a slide or shutter g movablein guideways in the flanges or lips it, 2' on the side bars a, b. Theopen frame is designed to hold a pack of films, of a size to fit snuglybetween the side bars a, b

and bear against the flanges h, i on said side bars, and the top bar ahas a cut-out portion 10, which cooperates with the upper edge of theback 0 to form a slot 12 (see Fig. 8) through which extend the tabs orprojections 13 on the film pack.

The pack holder as thus far described is designed to receive and firmlyhold a pack of films of one size, as for instance a 1x5 film.

In camera practice, it is often desirable to take pictures of manyobjects, but the user is oftentimes restrained on account of the expenseof the large size films, whereas if a smaller size of film could be usedin the holder, the expense would be materially lessened. For thispurpose I have provided an auxiliary or supplemental pack holdercomprising an open frame having side, top and bottom bars 15,16, 17 (seeFigs. 4 and 5) and lips or flanges 18 on the side bars 15.

The supplemental frame or holder is made to fit snugly in the open frameof the main holder as represented in Fig. 3 with the side bars of thesupplemental frame bearing against the flanges or lips 71, i of the sidebars of the main frame, for which purpose the flanges or side strips 18of the supplemental frame are secured or arranged on the side bars 15 ofsaid supplemental frame away from the outer edge of the same asufficient distance to permit the flanges or side strips 18 to pass bythe inner edge of the flanges h, i of the main frame, with the resultthat the strips or flanges 18 of the supplemental frame not only formfront supports for the smaller film pack (see Fig. 3) but also positionthe exposed film of the smaller pack in the same focus as the largerfilm pack.

The top bar 16 of the supplemental frame is made of such thickness thatits rear side or edge is substantially flush with the edge 10 of theslot 12 so as not to interfere with the tabs 18 passing through saidslot.

In Figs. 3, 4 and 5, I have shown one size of supplemental pack holder,which may be used with a film pack 20 of the next size to the one usedwith the main holder, say for instance 3 x li, but I do not desire tolimit my invention in this respect, as the supplemental frame may bemade so as to take care of much smaller film packs. Such supplementalholders or frames are shown in Figs. 6 and 7. In Fig. 6, the top andbottom bars 16, 17 are provided with flanges, strips or ledges 22, 23 aswell as the side bars, which leave an opening for the smallest size offilm pack, as for instance, a brownie 2 x8 whereas in Fig. 7 a slightlylarger opening is left by omitting the flange or strip 22 on the topbar.

In Figs. 6 and 7, it will be observed, that the side strips or flangesare secured or attached to the side bars within the outer edge of saidside bars, so as to permit the said flanges or strips to pass by theside bars of the main frame after the manner represented in. Fig. 3.

It will thus be seen, that a plurality of different sizes of film packsmay be used in a camera having a holder for the largest size of filmpack, by providing a supplemental holder or frame for each of thesmaller sizes of film packs, whose exterior dimensions are substantiallythe interior dimensions of the main holder but whose interior dimensionsare such as to correspond to the different sizes of film packs, yet havethe latter properly positioned in the main holder, so that theindividual films of the smaller pack can be removed the same as those ofthe larger packs.

1 have herein shown one construction of supplemental holder, which I mayprefer, but I do not desire to limit my invention in t is respect.

Claims.

1. The combination with a film pack holder, comprising an open frame, amovable back and a shutter in sliding engagement with said frame, of anauxiliary pack holder consisting of an open frame fitted within the mainframe and provided with side flanges or strips, substantially asdescribed.

2. The combination with a film pack holder, comprising an open frame, amovable back and a shutter, of an auxiliary pack holder fitted withinsaid open frame, substantially as described.

3. An auxiliary film pack holder, comprising an open frame provided withside bars between which the film pack is inserted, and flanges or stripsattached to one face of said side bars within the outer edge of the sameand projecting beyond the inner edge of said side bars, substantially asdescribed.

4:. An auxiliary film pack holder comprising an open frame within whichthe film pack is placed, and strips or flanges on said frame projectingWithin the same and against which the film pack bears, substantially asdescribed.

5. An auxiliary film pack holder, comprising an open frame consisting oftop, bottom and side bars, said top bar being thinner than said sidebars to leave a space for the projecting tabs of the film pack, andmeans to prevent the film. pack passing through said holder.

6. The combination with a film pack holder, comprising an open frame, ofan auxiliary pack holder fitted within the main holder and provided withmeans for preventing the film pack passing through the auxiliary holderwhile permitting the smaller films to be placed in the same focus as thelarger films, substantially as described.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
